v l SPECIFICATION forming parl: of Letters Patent No. 36].,3'72I dated April 19, l8p8'7.

Application filed September 151, 1886. Serial No. 213,777. (No model.)

To all whom t may concern:

Be it known that I, GEORGE PoTfrs, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

The object of my said'invention is to insure a perfect engagement of two sets of cogged 1o gears when employed in driving a single revolylingpart placed on the same shaft there wit It consists, essentially7 in the employment of apin or lrod which passes through said i 5 gears and said driven part and connects them together, as will be hereinafter more particularly described.

Referring to the accompanying drawings, which are made a part hereof, -and on which 2o similar letters of reference indicate similar parts, Figure l isa top or plan view of a portion ofa press in which my said invention is employed; Fig. 2,asideelevation ofthesame; Fig. 3, a central vertical section thereof on the dotted line 3 3 in Fig. l; Fig. 4, a horizontal sectional view through the parts particularly embodying my said invent-ion on the dotted line 4 4 in Fig. 3; Fig. 5, a detail sectional View through the pinions which drive the gear-wheels, their shaft, and a clutch part by which they are secured from rotating thereon; Fig. 6, a view in which is illustrated the use of my invention in connection With a plain eccentric instead of an eccentric gear, such as is used in the press; and Fig. 7 a similar Viewr is desired shall be driven by means of this in- `vention, and F a rod or bar connecting the gear-wheels and the device which they drive. The shaft is an ordinary drivingshaft,

and has pinions b b thereon, which, in the con struction shown, are held from rotating by a clutclr portion, b', placed between them and 5o keyed onto the shalt, as shown particularly in Figp.

.The shaft C is a plain shaft mounted in appropriate bearings in the framework. Upon it are placed the gear-wheels D D and the de 5 5 vice E, which is to be driven thereby. i The rod or bar F passes through the gearwheels Dand said device E, and secures their concurrent rotation. It is, however, made slightly loose in its bearings, (see particularly 6o Fig. 4,) and consequently the slight unevenness which is usually present iniv ordinary gearing does not operate to throT the force upon one or the other of the geariwheels, but, by reason of the slight oscillation which is permitted by` this looseness, a uniform and equal bearing is maintained between the severalv parts at all times, and all undue strain upon any of them is thus effectually prevented.

The operation :is as follows: The pinions b 7oy on the shaft B engage with the gear-wheels D and drive them either with or around the shaft C, (they being loosely mounted on said shaft,) and these Wheels, through the bar or rod F, drive the device E, which engages with and drives any mechanism desired. In the Aprincipalviews this device E is shown as a cogged segment which engages with a plunger to a press. In Fig. 6 it is shown as an eccentric, E', driving a pitman, and in Fig. 7 as a 8c cog-wheel, E2, driving an ordinary cogwheel; but itWill be understood that I do not desire to confine myself to either of these, or to any particularly device, but expect to use this invention wherever it can be employed in driving any part of a machine which is capable of being driven in the manner indicated.

It will also be readily seen thatiwhile I have shown the invention in connection with a baling-press, it is equally applicable to other 9o :machines-as7 for instance, brick-machines, tile-machines, and other machines of a similar nature.

Having thus fully described my said invention, what I claim as new, and desire to secure vice, and the pin or bar F, connecting said deby Letters Patent, isvice and said wheels together, substantially as l. The combination, with a mechanical deshown and described. vice, of two cog-wheels mounted on the same In witness whereof I have hereunto set my 5 shaft therewith and connected thereto by a hand and seal, at Indianapolis, Indiana, this 15 pin or bar passing through said device and 6th day of September, A. D. 1886.
